DBS-C01 Deployment and Migration Practice Question
A company is planning to migrate a 1 TB SQL Server database to Amazon RDS for SQL Server. Which TWO factors should be considered when choosing the migration approach?
⚠ Common exam trap
A common mix-up: candidates confuse operational factors (like concurrent users or version compatibility) with migration approach decisions, when the key differentiator is whether the source database schema and features are fully supported by the RDS platform.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The need to modify the database schema for compatibility
When migrating a SQL Server database to Amazon RDS, certain features like full-text search, CLR assemblies, or deprecated data types may not be supported or require schema modifications. RDS for SQL Server does not support all SQL Server features (e.g., FileStream, Service Broker, or cross-database references), so the schema must be reviewed and potentially altered to ensure compatibility before migration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The number of concurrent users accessing the database
Why it's wrong here
Concurrent users affect performance but not the migration approach.
- ✓
The need to modify the database schema for compatibility
Why this is correct
Schema changes may be required and SCT can assist.
- ✗
Whether the database uses SQL Server Agent jobs
Why it's wrong here
SQL Server Agent jobs can be migrated to RDS using SCT or recreated.
- ✓
The acceptable downtime window for the application
Why this is correct
Determines whether offline (snapshot) or online (CDC) migration is feasible.
- ✗
The version of the source SQL Server instance
Why it's wrong here
Version affects compatibility but not the overall migration approach choice.
